Abstract: Described herein are systems for mode switching in an appliance, and related analysis and reporting. Associated methods can include determining, by circuitry of an appliance, that an operation of the appliance is abnormal. The determination can include sensing the abnormality and identifying that the operation of the appliance is an abnormal operation according to the sensing of the abnormality. The methods also include switching, by the circuitry, the operation of the appliance to a safe mode. The safe mode can include reducing power used with the operation (such as to stop or reduce speed of rotation of a fan in the appliance). The method also includes communicating, by the circuitry, information regarding the abnormality and/or that the abnormality was resolved, to an electronic device and/or a server. The electronic device can display the information on a display device. The server can generate statistics according to the information.

Abstract: A blower device for use in an air purifier is disclosed. The blower device includes a first fan and a second fan which have a same air blowing direction and are arranged sequentially in the air blowing direction at an interval. The first fan and the second fan are mounted coaxially and driven synchronously by a motor.

Abstract: Disclosed is an air purifier and a wind tunnel thereof. The wind tunnel includes: a wind inlet; a wind outlet; a turbo fan arranged at the wind inlet for sucking into an air flow and blowing the air flow towards the wind outlet along an inner wall of the wind tunnel; an axial fan arranged at the wind outlet for discharging the air flow; and a flow-spoiler portion formed on the inner wall of the wind tunnel between the turbo fan and the axial fan, wherein the flow-spoiler portion spoils the air flow to make at least a portion of the air flow to be away from the inner wall of the wind tunnel when it is blown towards the axial fan.
